This invention relates to a supporting structure for acid bottles used as inclination detectors in rotary well drilling. It is an object of the invention to provide 5 an annular type of container for corrosive or marking liquid which may be supported in a tubular mounting.

A further object is to provide an acid bottle support in tool joints such as are commonly used in connecting the sections of drill stem together, in which the said bottle can be easily inserted and withdrawn.

The aim of thevinvention is to provide an acid bottle in which a record can be accurately made and which can be conveniently housedand supported. Referring to the drawing, a central longitudinal section through a tool joint is shown, equipped with the invention.

The tool joint'is made up-of the usual pin member 1, having a socket 2, threaded to receive the threaded end of a drill pipe secti'on, not shown. The lower end is reduced in diameter 'to provide a shoulder 3, and has a tapered pin 4, threaded with a coarse thread to engage within the socket or box 5, of the box member 6 of the tool joint. The box member 6 also has a threaded pipereceiving socket 7 to connect with the drill pipe. The two sections of the tool joint have a fluid passage 8 therethrough of comparatively small internal diameter to allow for strength in the stock of the joint. The box member has the passage recessed below the threaded box 5 as shown at 9 to receive the acid bottle 10.

The said acid bottle is annular in shape,

and of the proper internal and external di ameter to fit wlthin the recess 9 and not obstruct the passage 8. The bottle may be of any desired material designed to be etched or marked by the marking liquid to be placed therein. Said bottle may rest upon a spring washer or late 11 at the bottom of the recess 9 and l iav'ng upwardly bent tongues 12 thereon to resiliently support the bottle.

The bottle is adapted to be closed by an annular nut 13, threaded to screw into the walls of the recess and below the tapered box 5. Said nut has a downward projection 14 adapted to engage withinthe upper end of the bottle, and displacesoin'e-o'f theliquid I therein.

To protect the inner faceiof the bottle, a

thin rlng 15 of hard metal is use'd as a wall about wall as: at 16,-and thus constitute a skirt which protects the, bottle and closesfh'e recess. 1

In use the bottle is assembled in; the recess the inner side ofthe'j recess '9. This may be secured to'thenut bylweldin'g 9 as shown, the bottle-is partlyfilledwith corrosive or marking liquid adapted to make Y The rest of the bottle a line upon the bottle. is filled with a light gravity liquid, such as oil or gasolene adapted to float upon the acid. When the nut is then screwed inplace it will displace some of the light liquid into the recess 9 and close the upper end of the bottle thus acting to prevent splashing the marking liquid in use. The tool joint will be connected into the drill stem line and will be affected by inclination from the ver-.

tical and will mark a line indicating the level of the marking liquid. When the drill is withdrawn from the well, theline marked on the bottle by the marking liquid may be noted to learn the inclination of the drill stem. The use of the annular form of bottle makes it possible to obtain a more accurate record and also enables the bottle'to be used I in tool joints as described where it may be I easily accessible. I

What is claimed as new is I 1. An acid bottlefor declinometers com prising an annular container adapted to surround a tubular passage, and means to close the upper end of said bottle, acting also to fix said bottle in osition. I p

2. An acid ottle'for declinometers comprising anannular container'adaptedto surround a tubular passage, a plug to, close the upper end of said bottle, bottle in ositionand an annular projection on said p ug acting also the liquid in said bottle.

3. The combination of a tool central passage therethrough and a recess about said passage with an acid; bottle of annular shape in said recess, and aplugthread displace some of so f i acting also to fix said joint having a 1 ed in said' reoess and acting to close said bottle. I I

4. The combination of a tool joint having a central assage therethrough and a recess about sa d passage with an acid bottle of annular shape in said recess, and resilient means to support said b'Ot-fle5and a plug threaded in said recess and acting 't o close said bottle.

5.'The combination of a tool joint having about said passagewith anacid bottle of annular shape in said recess, and a plug threaded in said recess and acting to close said botrtle, said plug having; arskirt thereon to pro- '6.
